Description

  The present invention relates to a pest landing suppression method for suppressing landing of landing insects such as mosquitoes on the body surface of humans, livestock, etc., and obtaining a landing suppression effect, and a volatilization apparatus and a volatilization preparation used therefor .

  Conventionally, various drugs and control methods have been studied in order to protect animals such as humans, livestock, and pets from damage caused by pest biting behavior. One of them is aimed at repelling pests. For example, N, N-diethyl-m-toluamide, dialkyl phthalate, 2-ethyl-1,3-hexanediol and the like are known as repellents, and examples using these include N, N-diethyl-m-toluamide and Pest repellent containing castor oil (Patent Document 1), pest repellent containing N, N-diethyl-m-toluamide and 1S, 3R, 4R, 6R-curan-3,4-diol (patent) Reference 2) and the like.

  However, these pest repellents cannot suppress flying pests from landing on the body surface of humans, livestock and the like. For this reason, even if the pest sucking action can be suppressed, there is a problem that the discomfort caused by the pest landing remains.

In order to volatilize an insecticide by a volatilization amount that is extremely lower than the amount at which knockdown activity or insecticidal activity is manifested, various methods can be employed, and examples include the following methods.
(1) Hold an insecticide such as a high-temperature volatile insecticide on a carrier and volatilize it with air at room temperature.
(2) A room-temperature or high-temperature volatile insecticide is contained and retained in the resin, and is volatilized by wind at room temperature.

The high-temperature volatile insecticide described in (1) above refers to an insecticide having a vapor pressure of 1.34 × 10 ⁻³ Pa (20 ° C.) or less, and normally does not evaporate unless heated. As such high-temperature volatile insecticides, that is, agents that are hardly volatile at room temperature, among the above-mentioned insecticides, insecticides whose general names are phthalthrin, resmethrin, permethrin, phenothrin, fenvalerate, benfluthrin, fenpropatoline, etc. Is mentioned. Such a high-temperature volatile insecticide is used by being held on a carrier. When the carrier is a solid carrier, the pesticide is used as it is or dissolved in a suitable solvent and applied to the surface of the carrier, for example, held on the surface of the carrier, or impregnated inside the carrier and dried. That's fine.

  Such a carrier is not particularly limited. For example, paper, nonwoven fabric, woven fabric, wood, pulp, inorganic polymer material, inorganic porous material (silicate, silica, zeolite, etc.), organic polymer, etc. Substances (cellulose, polyethylene, polypropylene, polyvinyl alcohol, etc.), gelling substances (agar, carrageenan, gelatin, etc.), sublimable substances (adamantane, cyclododecane, paradichlorobenzene, naphthalene, camphor, etc.), resins, oil-based solvents, aqueous A solvent etc. are mentioned, These 1 type (s) or 2 or more types can be used in combination.

  In addition, the shape of the carrier is not limited, and can be used in various forms and shapes for use indoors, outdoors, in the car, tents, storage sheds, etc. It should be used. Such forms include, for example, a fan or fan in which a paper portion is impregnated with an insecticide, clothes made of nonwoven fabric or woven fabric (shirts, pants, skirts, jackets, work clothes, etc.), hats, parasols, gloves, Socks, wristbands, yukata, outdoor equipment (tents, hoodies, shruffs, etc.), armbands, armbands, pet wear, mosquito nets, hammocks, climbers, flags, etc. Other shapes of the carrier may be, for example, a tubular shape, a honeycomb shape, a slat-like shape, a lattice shape, or a net shape from the viewpoint of air permeability and sufficient drug retention. In this case, it is particularly suitable for installation in a passage through which the wind forcedly generated by the blowing means passes. Examples of the air blowing means include a fan, an air conditioner, an air cleaner, and a cold air fan. Further, the fiber mat may be impregnated. The high temperature volatile insecticide is held at a ratio of 0.5 to 50 parts by weight, preferably 1 to 20 parts by weight, with respect to 100 parts by weight of the carrier.

Moreover, the aspect which makes a resin contain and hold | maintain the said (2) normal temperature thru | or high temperature volatile insecticide, and volatilizes with a wind at normal temperature is demonstrated below. Insecticides, in particular, room temperature volatile insecticides, volatilize easily at room temperature, and thus are contained in the resin to control the volatilization amount. Here, the room temperature volatile insecticide is an insecticide excluding the above-described high temperature volatile insecticide, and means an insecticide having a vapor pressure lower than 1.34 × 10 ⁻³ Pa (20 ° C.).

Examples of the resin include polyethylene, polypropylene, polyvinyl chloride, polyurethane, acetal resin, polystyrene, polyamide, polycarbonate, and the like. The resin to be used is used in the form of a resin preparation having a specific surface area of 10 to 500 g / m ² , a thickness of 0.01 to 5 mm, and an opening area ratio of 0.3 to 0.8 in order to control the volatilization amount. However, the amount of volatilization is controlled by adjusting the specific surface area and the size of the open area according to the insecticide used. The opening area ratio can be obtained from the opening area per projected area.

  In order to contain an insecticide in these resin preparations, a predetermined amount of an insecticide is kneaded into the raw material resin and shaped into a predetermined shape as necessary. Content of an insecticide is 0.5-50 weight part with respect to 100 weight part of resin preparations, Preferably it is 1-20 weight part. In addition to using the resin preparation as it is, it is used by retaining at least a part of the carrier by impregnation or sticking.

  The obtained resin preparation can be used in various forms for indoor, outdoor, in-car, shed, storeroom, tent, etc. For example, insect repellent net preparation, fan fan preparation, fan fan preparation, air conditioner mounting preparation , Air purifier mounting formulations, fan mounting formulations, cold air fan mounting formulations, door mounting formulations, screen door mounting formulations, micro-dropping devices for blowing means (piezo fans, axial fans, sirocco fans, etc.), blowing of the blowing means Examples thereof include a device for feeding and winding the resin formulation to the road.

  Insect repellent net formulations are used by forming a net with the resin formulation or by attaching a resin formulation to one or both sides of the net. Fan fan preparations and fan fan preparations are used by sticking a resin preparation on one or both sides thereof. Insect repellent nets are a natural wind, and fan fans and fans are winds generated when they are blown.

  For the air conditioner mounting preparation, the air cleaner mounting preparation, the fan mounting preparation, and the cold air fan mounting preparation, for example, a resin preparation may be installed in front of the air outlets so that the wind hits the resin preparation. In the door-attached preparation, a chemical preparation is attached to at least a part of one or both sides of the door, and the medicine is volatilized by wind generated when the door is opened and closed. In the screen door-attached preparation, the chemical agent is volatilized by opening and closing the screen door and by the wind passing through the screen door by sticking a resin preparation on at least a part of one side or both sides.

  The very small amount dropping device to the blowing means drops a very small amount of the insecticide component on the fan portion of the blowing means and volatilizes it. In this case, the insecticide component is added dropwise in the form of a pesticide raw material not containing a solvent, a solution dissolved in a solvent, or the like. The device for feeding and winding the resin formulation to the air passage of the blowing means feeds out a necessary amount of the tape-like formulation and exposes it, and after the insecticidal components are volatilized, the exposed portions are sequentially wound. Further, as long as the volatilization amount is kept extremely low and the volatilization amount is effective for suppressing the pest landing, the volatilization amount can be used by sucking it up with a liquid absorbent core and volatilizing it at room temperature or heating.

  In addition, the resin preparation is attached to a carrier such as paper, nonwoven fabric, woven fabric, wood, pulp, inorganic polymer material, inorganic porous material, organic polymer material, gelling material, sublimation material, and resins. It can be retained by impregnation. The carrier can be used in various forms such as clothes, hats, parasols, gloves, socks, wristbands, yukata, outdoor equipment, armbands, armbands, pet wear, mosquito nets, hammocks, and bags. Alternatively, the resin preparation may be molded into a predetermined shape or held on a carrier having a predetermined shape and attached to the body surface. For example, it is formed into a band shape, hung from the waist, wrapped around the waist, hung on the shoulder, attached to the body surface using an adhesive or the like like a emblem, or sandwiched by a clip-like object.

  The volatilization preparation according to the present invention can also be used in the form of a liquid preparation in which an insecticide component is dissolved in an insecticide base or a solvent such as an organic solvent as described above. Examples of the solvent for preparing the liquid preparation include alcohols such as water, methanol, ethanol, isopropanol, and ethylene glycol monomethyl ether, ketones such as acetone, methyl ethyl ketone, and methyl isobutyl ketone, methyl acetate, ethyl acetate, butyl acetate, Esters such as diethyl phthalate, isopropyl myristate, butyl stearate, aliphatic hydrocarbons such as hexane, kerosene, paraffin, kerosene, n-pentane, isopentane and cyclopentane, and aromatic hydrocarbons such as benzene and xylene And ethers such as ethyl ether, ethylene glycol, and ethylene glycol diethyl. Two or more of these solvents may be mixed and used.

  A solubilizer or emulsifier can be used to solubilize or emulsify the active ingredient. Examples of the solubilizer or emulsifier include sorbitan trioleate, polyoxyethylene monooleate, polyoxyethylene nonylphenyl ether, polyoxyethylene (10 to 40 mol) hydrogenated castor oil, tripolyoxyethylene alkyl ether, 1, 3-butylene glycol, decaglycerin monooleate, propylene glycol dioleate, polyoxyethylene (16 to 20 mol) stearic acid amide, polyoxyethylene polyoxypropylene glycol, polyoxyethylene lauryl ether phosphate, glycerin fatty acid ester, etc. In addition, various surfactants such as stearyl alcohol, polyvinyl pyrrolidone, and lanolin fatty acid may be used, and these may be used in combination of two or more.

  The method of the present invention can be used to prevent or suppress damage caused by various sanitary pests, agricultural pests, and unpleasant pests. Pests to which the method of the present invention is applied include, for example, mosquitoes such as Sinohada araka, Akaieka, Kogaka Aikaeka, Aedes aegypti, Aedes albopictus, Aedes albopictus, etc .; , Yellowtails such as Kioshiobyu, Aokitsugegebuyu; Nukaka such as Tokunagaronukaka, Oshimamanukaka, chicknutka;
